I remember reading a study about different navigation strategies. In one strategy you developed a mental map of the area and you mentally navigated that map as a means to navigate the real world. Another strategy was the landmark strategy where you would learn procedural directions between landmarks and so navigation relied much less on mental maps and much more on procedural memory. I suspect these different strategies are at play in the responses noted in the study.
